I'm really only familiar with clen in pill form. But, yes it can really help take off fat all over the body. Diet is key though. Eat clean, don't cheat, and put yourself in a slight caloric deficit. Try doing cardio 3x per week and lift 4-5 times a week. You won't get bitch tits or anything from it but be sure you're in good health before you take it as it does put some extra strain on your heart. I find it a lot less noticeable than eca and a lot more comfortable. Good shit.
